Definitions

  • the present invention relates to an RFID monitor system, and more particularly to an asset monitor system.
  • the radio frequency identification (RFID) applied to a zone location are divided into two groups. The first one is RFID reader location and the second one is IR (infrared rays) location.
  • RFID radio frequency identification
  • the RFID reader location a plurality of RFID readers are installed in monitored spaces and radiated power of the RFID readers are set to adjust the coverage area.
  • the RFID readers are connected to a rear terminal by a network, and the RFID readers receive a signal sent from a remote tag to acquire a location of the tag.
  • the RFID reader location is unfavorable to apply in an accurate small-area location because of higher cost for using a large number of RFID readers.
  • a plurality of IR transmitters are installed in monitored spaces.
  • the IR transmitter sends a location identification to an electronic tag with an IR receiver, and the electronic tag transmits a signal included the location identification to a reader.
  • the location identification easily disappears when the IR receiver of the tag is covered by clothes or other objects.
  • ZigBee is a wireless technology developed as an open global standard to address the unique needs of low-cost, low-power, wireless sensor networks.
  • ZigBee has two main disadvantages: first one is a large number of data are received by readers to increase electricity consumption of electronic tags. The second one is a plurality of routers are used to pass through responded messages to increase difficulty of certifying the actual location.
  • a primary object of the present invention is to provide a system and a method for a RFID asset monitor.
  • a router is installed between a reader and a tag. The router can automatically sends a location identification to the tag, and afterward an original identification of the tag and the location identification of the router are sent to the reader, or indirectly forwarded via the router to acquire a location of the article.
  • the asset monitor system comprises a tag, a reader, and a router.
  • the tag is mounted on an article or a user.
  • the reader is provided to receive a signal responded from the tag, and the router is installed in a desired place.
  • the router automatically sends a location identification to the tag, and the location identification is received by the tag; the location identification is stored and directly sent to the reader or indirectly forwarded via the router.
  • the asset monitor method comprises that a router transmits actively a location identification to a tag in a coverage area. Afterward, the tag receives the location identification in the coverage area, and determines whether the tag sends a signal or not. Afterward, the tag sends directly the signal to the reader or forwards indirectly to the reader via the router.
  • the asset monitor system is a mesh network system, and the router can be provided to transmit a signal for another router; a signal received from the remote tag is transmitted to another nearby router, and the signal can be transmitted to another router near the reader and afterward the signal is transmitted to the reader by the router to acquire a location of the article (or the user).
  • Fig. 1 is a block diagram of an asset monitor system according to the present invention.
  • the asset monitor system comprises a reader 1, a router 2, and a tag 3.
  • the asset monitor system is a mesh network system, and the router 2 is installed between the reader 1 and the tag 3.
  • An original identification of the tag 3 and a location identification of the router 2 are sent to the reader 1, or indirectly forwarded via the router 2 to acquire a location of the article 5.
  • the reader 1 is a reader apparatus of a conventional radio frequency identification (RFID) and is provided to receive signal responded from the router 2 or the tag 3.
  • RFID radio frequency identification
  • the router 2 automatically sends a location identification to the tag 3 in a coverage area.
  • the router 2 can transmit the location identification to the tag 3 by using a time-setup way or externally triggering the router 2.
  • a radiated power is set by the router 2 to adjust the coverage area where the location identification can be received by the tag 3.
  • the tag 3 is a tag apparatus of the conventional radio frequency identification (RFID) and is mounted on a user or an article 5.
  • the tag 3 receives the location identification transmitted from the router 2 and the location identification is stored in a memory 31.
  • the location identification and an original identification of the tag 3 are transmitted to the router 2, and afterward transmitted to the reader 1; or the location identification or the original identification are transmitted directly to the reader 1 to acquire a location of the tag 3.
  • the tag 3 directly sends a signal to the reader 1 or indirectly forwards to the reader 1 via the router 2 when the location identification of the tag 3 is different from a current location identification or the location identification is repeatedly received up to a preset value.
  • the signal can be sent by the Internet or an RS232, and afterward stored in a database of a host (not shown) to monitor the current location of the tag 3.
  • a router actively and periodically transmits a location identification to tags in a coverage area (S100), or the router is triggered by an external input to transmit a location identification to a tag in a coverage area (S102).
  • the location identification is stored in a memory after the tag receives the location identification (S104).
  • a location of the tag is determined to have changed or not (S106).
  • a signal is directly transmitted to the reader, or indirectly forwarded via the router when the location is changed (S108).
  • the signal includes an original identification and the location identification of the tag.
  • the location identification is checked whether it is repeatedly received up to a preset value when the location is not changed (S110). The procedure returns to the step (S104) when the location identification is not repeatedly received.
  • a signal is directly sent to the reader or indirectly forwarded via the router when the location identification is repeatedly received up to a preset value (S108).
  • Fig. 3 is an application schematic view of the asset monitor.
  • the two routers 2,2' are installed in two spaces 4,4', respectively, and the location identifications of the routers 2,2' are set as "0001" and "0002", respectively.
  • the tag 3 is mounted on an article 5 (or a user), and it assumes that the location identification currently stored is set as "0000".
  • the router 2 actively transmits the location identification set as "0002" to the tag 3 when the article 5 is placed in the space 4'.
  • the new location identification set as "0002” is stored when the location identification set as "0002" is different from the current location identification set as "0000".
  • the tag 3 directly sends a signal to the reader 1 or indirectly forwarded via the router 2, 2'.
  • the signal includes the location identification set as "0001" and the current location identification to acquire that the article 5 is placed in the space 4'.
  • the location identification is changed by the tag 3 when the article 5 is moved to the space 4. Afterward, the tag 3 directly sends a radio frequency (RF) signal to the reader 1 or indirectly forwards to the reader 1 via the router 2, 2'. An operator acquires that the article 5 is moved to the space 4 when the reader 1 receives the location identification set as "0001" and the current location identification.
  • RF radio frequency
